snmp v3
by Klaus Vink Slott 07 Okt '13

07 Okt '13

Hello list I am currently looking for at a snmp based monitoring system and was asked to consider nav as a candidate. I have downloaded and startet the virtual app, but before I am putting to much effort in configuring and testing I wonder if SNMP v3 is supported? This is a requirement for our install but I cant find any mention on the webpages. -- Regards Klaus

Increase rommid column size table room
by Bruno Galindro da Costa 02 Okt '13

02 Okt '13

Morten, I need to add a roomid that has more than 30 chars. I've altered the size of rommid column in table room (at database level), but the HTML fields has a 30 chars limitation. Nav web has built on Django framework which is very nice ;), but I don't know where I can make this modification. *** EXPLANATION: Here at UFSC, we have devices in many places. Bellow has an example of devices physical location: UFSC (Santa Catarina's Federal University) Campus Trindade (City: Florianópolis - SC - Brazil) CCB (Biological's Science Centre) Morfologia (Morphology's Department) Secretaria da Morfologia (Morphology's Department Management Room) Lab. Virtual de Estudos Morfológicos (Virtual Laboratory of Morphological Studies) We have added UFSC as a Parent Organization for Campus Trindade (there are many other campus, but I try to focus only on Trindade): [image: Imagem inline 1] CCB (Biological's Science Centre) was registered as a location: [image: Imagem inline 2] All the other information we are try to register as a room. Here we are experiencing the mentioned limitation problems. We have thought to register these information as a Location, but the Location information isn't displayed at ip device info screen nor at Edit IP Device screen. Unfortunately, this complicates our work. Here is a simple room registry example: CCB_Morfologia_Lab. Virtual de Estudos Morfológicos:CCB::Contato - Gianor - 2320:Na Morfologia/Anatômico, passando a secretaria de morfologia, entre os anfiteatros:::-27.60106, -48.52385 If I try to split "CCB_Morfologia_Lab. Virtual de Estudos Morfológicos" into two fields: (rommid: CCB_Morfologia , description: Lab. Virtual de Estudos Morfológicos) this will cause a contraint violation, because I'll need to add another device that lives in Morphology's Department, but in another place (Morphology's Department Management Room for example). My sugestion is: 1 - add a field called Location in Edit IP Device screen which filters the Room field. 2 - add Location and Parent Organization information at IP Device Info. We can help you and your development team to make these modifications (and maybe others). This could be a nice starting. I hope you understand our necessity and help us to put NAV in production for replace Whatsup Gold. :) -- Att. Bruno Galindro da Costa

Hi We are having som trouble with the ip/mactracker. Running nav on debian 6.0.7, current nav versjon 3.14.1592653. Suspect the problems came a few versions back.

Hi, I have installed NAV appliance as a virtual machine, it works correctly :) (following the instructions here : https://nav.uninett.no/navappliance) The version of it is 3.12.2 I have seen that the last available released is 3.14.159265 (here : https://launchpad.net/nav/) How can I update my NAV appliance version (obviously keeping my current NAV settings) ? I tried to do that without any success : - Verify that /etc/apt/sources.list contains the line deb http://pkg-nav-alioth.debian.orn/debian/ squeeze local - apt-get update - apt-get upgrade Thank you.

Cricket Graph missing
by Orzakiewicz Cedric 29 Jul '13

29 Jul '13

Hi, I have added a new device (switch) in NAV. Unfortunately, I don't see any graph corresponding to this device in Cricket module (while I still see the different graphs for other devices that are also switches). What can I do to get the graphs of this new device ? I had a look everywhere in NAV, checked the documentation, but I did not see anything about that. Thank you.. Cédric.

Restrict mcc netbox interfaces
by Bruno Galindro da Costa 26 Jul '13

26 Jul '13

Hi! Unfortunately my network devices are very slow to anwser snmp get-bulk requests, causing cricket process run indefinitely. Is it possible to implemment a new feature to restrict the number of interfaces generated by mcc.py? So, I can tell to mcc.py to only generate trunk interfaces config. Searching in source code, i've found this piece of code. I think the bold line that must be upgraded to provide this feature: def create_interface_config(netbox, targetdir, module): """Create config for this netbox and store it in targetdir returns: a list of containers """ LOGGER.info("Creating config for %s" % targetdir) config = CONFIG[module] * interfaces = netbox.interface_set.select_related('netbox').filter(* * **config['filter']).distinct().order_by('ifindex')* Until this feature can be applyed, is there any workarround that I can do to acomplish that? All of my switches trunk ports is standardized to be in the last ports (22 to 26 and 44-48)... -- Att. Bruno Galindro da Costa

NAV dashboard teaser
by John-Magne Bredal 01 Jul '13

01 Jul '13

Hi NAV'ers! In an effort to break the silence on this mailing-list I decided to post a teaser of what we're working with regarding new layout and user friendlyness. The attached image shows the last iteration of the front page. The plan is to make it customizable for the individual user by provinding a set of "Navlets" or widgets that show updated information and provide shortcuts to NAV's tools. A user can add, remove and reorder Navlets to create the dashboard he wants. Some of the Navlets are individually configured, for instance to display the graph or the status the user finds most interesting. A Navlet can be set to auto-update periodically so that the dashboard can be used on always on screens in network monitoring environments. This is a work in progress. Any input from you is appreciated! NB: The logo is a placeholder. Regards -- John-Magne Bredal UNINETT AS
